Festival between land and sea in Plomodiern
Sea Fest'N Sound is a music festival between land and sea held every summer in Plomodiern, on the Dour Frout site near Lestrevet beach. Created in 2017 by the association IDM, this friendly festival offers an eclectic program mixing rock, Celtic music, folk, and world music. Facing the bay of Douarnenez, it brings together hundreds of festival-goers each year for two days of live music and artistic discoveries.
Since 2017, Sea Fest'N Sound has enlivened the Plomodiern coastline every summer with a music festival rooted in its territory. Located on the Dour Frout site, a stone's throw from Lestrevet beach and facing the majestic Bay of Douarnenez, this festival offers a spectacular natural setting between land and sea.
Sea Fest'N Sound stands out for its open and varied program. Rock, Celtic music, folk, reggae, world music: each edition invites artists from different backgrounds to share the stage. In 2025, the 7th edition featured The Celtic Social Club, Les Sales Majestés, RedBones, Cutting Corners, The Bloyet Brothers, and many other local and regional artists.
The festival is organized by the IDM association (Initiation and Discovery of Music), an associative structure that works throughout the year to promote musical culture in the Menez-Hom Atlantique region. Beyond the festival, the association offers musical initiations and discovery activities for all audiences.
